Brushes Into Pse8 On Mac

Hi girls! Last Christmas I got a MacBook that I use strictly for Photos and Photoshop. Since I'm not using it daily I still consider myself a newbie and have been stumbling along with Elements without using my styles and brushes. After much research I finally figured out how to install and show the styles, now I'm ready for the brushes. I don't find a presets folder as the PC version does. What am I missing?! How do I install the brushes I have? Thanks much!!
